Application filed. December 14, 1922. Serial No. 606,945.

Sometimes called reeds, desi ned for leno weaving, and more particu arlyto the needles employed therein. g

In leno frames it is common to forwardly offset between alternate dentsbroad needles whose upper ends have a continuous unbroken bevel orincline extending the entire width of the needle shank forming aresultant apex with the offset needle portion. T .One of the pair ofwarp threads traverses a needle eye while the second or disengaged warpthread is, by the harnesSesQliftedover the needle point and thendownwardly between its needle and its right hand adjacent dent, and isnext elevated over the needle point and then downwardly between itsneedle and its adjacent left hand dent, thus alternatingcharacteristically of the leno weaving art. Thedescribed'needle endpermits the accidental escapeof the disengaged warp thread. Furthermorethe point of'the needle often becomes laterally bent so that its/bevelededge either contacts with or in clines laterally towards an adjacentdent so that the disengaged warp thread isinducedfto reciprocatevertically at one side of the needle, rather than to reciprocatealternately at both sides of the needle.

The essential objects of my invention are to overcome the -aboveenumerated disadvantages.

To this end essentially my invention consists in such parts and in suchcombinations of parts as fall within the scope of the appended claims. r

In the accompanying form a part of this specification Figure 1 is afragmentary front elevation of a heddle embodying my invention,

Figure 2, a section of the same on line 22 of Figure 1,

drawings which Figure 3, an enlarged perspective View of the upper endofthe needle, and

Figure 4 a like elevation of a needle and adjacent dents showing athread engaging the needle.

'ke reference characters indicate like parts throughout the views.

In the drawings 8 represents the heedle frame of any usual preferredconstruction including the common flatmetallic dents or separators 10mounted therein. -Located between the. dents and fastened thereto at- Ktheir lower ends in the frame are needles 12 which alternate with thedents. The needles are shorter than the dents and are sufficientlybroader than-the latter to extend. beyond and in front of the plane ofthe forward edges'of the latter.

. Each needle is of thin flat metal comprising a broad body portion 14'having upon its upper end a vertical finger 15 formed in its forwardlateral margin. The upper end -17 of the finger is downwardly and rear-Wardly beveled from the forward'edge 18 of the needleforming anacutepoint'l9. The 7 rear edge 20 forms an abutment or shoulder.

Extending from the base of the finger 15 is a downwardly and rearwardlyinclined shoulder 21 extending to the rear edge 22 of the needle. 24 isthe usual needle eye through which passes one of the two warp threads,not shown. The other orfdiseng'aged, warp thread 26 is herein shown infull lines' atone side of a needle, and in broken lines at the oppositeside :of the needle in Figure- V g It will be observed byreference toFigures 2 and 4:.that. the vertical finger 15 is parallel withthe dents,and located in frontthereof and spaced therefrom as at 27. Hence even ifthe finger 15 becomes laterally bent it will not contact with theadjacent dent but the warp thread will pass'through the space. 27 andthence downwardly. I v

Futhermore the advanced finger 15'wholly spaced from the dents forwardlythereof not only makes engagement'of the thread certain, but acts as apositive guide which assists to force the thread down between the needleand dents. This enables the dents to be set closer together and thusincreases the number of dents possible in a single frame. a y

In testimony whereof I have affixed signa- 20 ture.
